, Specification of Letters Patent.

Patented May 21, 1912.

Application filed June 6, 1911. Serial No. 631,565.

To all whom it may concern:

Be it known that I CARY A. NEYILAND, a citizen of the United States, and a resident of Spokane, in the county of Spokane and State of Washington, have invented a new and Improved Current-Motor,of which the following is a full, clear, and exact description.

The invention relates to current motors, such as shown and described in LettersPatent of the United States,'No. 880,393 and No. 930,878, granted to me on February 25, 1908, and August 10, 1909, respectively.

The object of the invention is to provide a new'and improved current motor, more especially designed for use on a flowing stream, tide water or other moving body of water, and arranged to actuate a pump or other mechanical contrivance in a very ef-' fective manner, and to utilize the force of the moving body of water to the fullest advantage. For the purpose mentioned use is made of a sweep beam connected with a mechanical contrivance such as a pump and with a paddle arm carrying a paddle adapted to be acted on by the force of the moving body of water to imp-art a swinging motion to the said paddle arm, which latter is connected with a counterbalancing device and with an adjustable controlling device for controlling the dip of the paddle in the water. Use is also made of a specially constructed pump having a conduit pipe terminating in an inclined hollow plunger on which is mounted to slide a cylinder connected with the sweep beam so that the cylinder is drawn up on the plunger by the force of the water acting on the paddle, and during the return stroke of the paddle the cylinder by its own weight returns to lowermost position thus returning the sweep beam, paddle arm and paddle to starting position. A practical embodiment of the invention is represented in the accompanying draw"- ingsforming a part of this specification, in which similar charactersoffreference indicate corresponding parts in all the views.

Figure '1 is a plan view :of the current motor and showing the parts in position at the beginning'of the'working stroke of the paddle; Fig. 2 is a side elevation 'of the same; Fig. 3 is a rear view of an adjustable controlling device for controlling the dip of ning 0? and Fig. 6 is an enlarged cross section of the parts in position on thereturn stroke of the paddle; Fig. 5 is a like view of thesame showin the parts in position at the beginthe working stroke of the paddle;

cylinder pump.

An inclined railway track A is anchored on the shore B of a waterway, to extend into the water a sufficient distance for the proper operation of the current motor, and on the said track A is mounted to travel a carriage G supporting the motor proper. On the carriage C is mounted a pump consisting essentially of a cylinder D mounted to slide on an inclined hollow plunger E connected by an elbow E with a horizontally-disposed conduitv pipe E extending from the rear end of the carriage G to the adjacent land, to deliver the water to a reservoir or other receiver. The conduit pipe E is provided adjacent to the elbow-E with a check valve E to retain the water in'the conduit pipe E? during the down stroke of the cylinder D on the plunger E, and the conduit pipe E in the rear of the check valveE is provided with a suitable air chamber E* to maintain a pressure on the water in the conduit pipe E I The cylinder D is provided in its lower end with a suction valve D, and the cylinder is encircled by aband D provided with sidewise extending shoes D mounted to slide on bearings C forming part of the carriage C and inclined thereon to correspond to the inclination given to the plunger E, as will I with: the sweep beam G- ;and' is attached to one end of'a spring G secured at its other end to the carriage C so as to hold the sweep beam G under tension.

A paddle arm H- extends longitudinally and is provided'at: its forward endwith'a paddle H? while its rear end ispivotally connected by ball and socket joint I. H with the sweep beam Gr adjacent to the fulcrum G, and the said paddle arm H is connected at its forward portion by a number of stays H with the upstream end of the sweep beam G. A stay H is connected at one end with the paddle arm H at the down-stream side, and is connected with a spring H attached to the lower end of the sweep beam Gr so as to hold the paddle arm H under tension, so that a swinging motion given to the paddle H by the force of the body of water, causes a rocking motion of the sweep beam G for the latter to exert a pull on the chains F with a view to draw the cylinder D upward on the plunger E. Instead of the spring H a weight may be attached to the stay H The stays H and H may be in the form of rods or cables.

An upwardly-extending chain I connects the paddle arm H with a yard arm J provided with a pivot pin J journaled in bearings K attached to the upper bifurcated end of a stanchion K erected on the forward end of the carriage C and held in place by suitable braces K K as plainly indicated in Figs. 1, 4 and 5, the stanchion K and the brace K also supporting rungs K for forming a ladder to permit of reaching the top of the stanchion K for repairs or other purposes. The yard arm J extends transversely and is provided at its free end with a weight J 2 held adjustable on the yard arm by a set screw J 3 or a similar fastening means. The pivot pin J of the yard arm J is preferably mounted in a block J attached to the top of the yard arm J and braced by a truss rod J and the under side of the yard arm J is preferably concave as at J 6 so that the yard arm J is free to swing on the stanchion K. While locating the pin J in the block J 4 above the top of the yard arm J the latter readily balances.

In order to control the dip of the paddle H in the water use is made of an adjustable controlling device arranged as follows: On the paddle arm H is erected a post L extending through a loop N held on a transversely-extending swing arm N provided with a chain N secured at its ends to the top of the swing arm N and engaging with one of its links a hook N attached to the stanchion K (see Fig. 8). A pin N asses through the loop N and engages one of a series of apertures L formed on the upper portion of the post L, so that the swing arm N can be adjusted at its loop N up or down on the post L. The chain N engaging the hook N forms an adjustable fulcrum for the arm N by engaging any one of the links of the chain N with the said hook N and in doing so the post L is more or less inclined to turn the paddle arm H on its pivotal connection H with a view to give more or less inclination to the paddle H, thereby controlling the dip of the paddle in the water. The post L is connected by suitable braces L with the paddle arm H, as shown in the drawings.

The operation is as follows: Assuming that the flow of the water in the waterway is in the direction of the arrow at (Fig. 1) and that the carriage C is positioned on the track A so as to permit a proper submergence of the paddle H in the current of the stream: now when the paddle H is in position for immersion the sweep beam G is disposed at right angles to the conduit pipe E plunger E and cylinder D, with the cylinder D in lowermost position. Upon the immersion of the paddle H the force of the current of water causes a swinging of the paddle arm H so as to rock the sweep beam G in the direction of the arrow 6, whereby a pull is exerted on the chains F and the cylinder D is drawn upward thus forcing the water in the plunger E up and into the conduit pipe E past the check valve E The paddle H extends farther from the lower side of the arm H than the upper side thereof, and the depending portion of the paddle H is acted on by the current of water to feather the said paddle H to such an extent that when the paddle H reaches the full extent of its rocking movement in the water then the paddle H is disposed vertically, and as the paddle arm H is rocked by the paddle H the post L by-its engagement with the swing arm N gradually turns the paddle H to such an angle that the force of the water throws the pad dle H upward and out of the current. The weight J of the balancing yard arm J is now free to act, thus imparting a swinging motion to the yard arm J whereby an upward swinging movement is given to the paddle arm H thus holding the paddle H out of contact with the water during the return swinging movement of the paddle arm H caused by the weight of the arm H and its paddle H aided by the springs G and H From the foregoing it will be seen that during the working stroke of the paddle H, while being submerged in the current of water, an upward sliding movement is given to the cylinder D to force the water from the plunger E into the conduit pipe E and during the return stroke of the paddle H, while out of the current of water, the cylinder D is free to slide downward of its own weight and refill with water by way of its suction valve D.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
